The answer to 'best time for mulch' is that the best time to apply mulch is in the spring or fall. In the spring, apply a 2-4 inch layer of mulch around your plants and trees to help retain moisture and suppress weeds as the growing season begins. In the fall, a fresh layer of mulch will insulate plant roots and protect them over the winter. Mulching in the fall also helps prevent soil erosion and compaction during the rainy season.
Applying mulch at the right time of year is important for the health and appearance of your landscaping. Mulch provides many benefits, but it needs to be refreshed regularly to continue working effectively.
